Returns a string containing the regular expression and its options (using the (?opts:source) notation. This string can be fed back in to Regexp::new to a regular expression with the same semantics as the original. (However, Regexp#== may not return true when comparing the two, as the source of the regular expression itself may differ, as the example shows). Regexp#inspect produces a generally more readable version of rxp.
Example
r1 = /ab+c/ix #=> /ab+c/ix s1 = r1.to_s #=> "(?ix-m:ab+c)" r2 = Regexp.new(s1) #=> /(?ix-m:ab+c)/ r1 == r2 #=> false r1.source #=> "ab+c" r2.source #=> "(?ix-m:ab+c)"
